一、Tools Preparation

• A suitable sealant (mildew-proof type is better for kitchens/bathrooms)
• A caulking gun (available on Taobao for tens of yuan)
• A wet tissue or cloth
• A cup of soapy water or detergent water
• Waste paper or a rag for wiping fingers

二、The Key to Perfect Sealant Application: Three Steps

1: Cut the Nozzle Moderately to Control Flow

• Use a utility knife to  (at a 45° angle) cut the nozzle to a moderate opening size based on the desired line thickness. Start with a small opening and expand it if needed—too large an opening makes control difficult.
  🌟 Tip: A 45° angled cut helps the nozzle hug the gap tightly when applying.

 2: Apply Sealant Steadily in One Go

• Load the sealant tube into the caulking gun, align it with the gap edge, apply even pressure to the handle, and move at a steady pace to ensure a full, continuous bead. Avoid stopping midway to prevent lumps.

3: Smooth with a “Soapy Finger” for a Polished Finish

• Dip your finger in soapy water or detergent (to prevent sticking), then gently run it along the fresh sealant bead. Use the natural curve of your finger to press and smooth the edge, creating a seamless transition with the surface.
  • Do not wipe back and forth—one pass is best.
  • If sealant gets on surrounding areas, wipe immediately with a wet tissue.
  • Use waste paper to wrap your finger and remove excess sealant.
    🌟 Key Point: No tape needed—achieve professional-level neatness with just your finger!

三、Drying Time & Precautions

• Surface dry time: Typically 10–30 minutes (avoid touching during this period).
• Full curing time: About 24 hours (check product instructions for specifics).
• Work in a dry, ventilated area—low temperatures or high humidity may extend drying.

四、Wide Applications to Save Renovation Costs

• Gaps between washbasins and walls
• Toilet base sealing
• Window sills and glass edges
• Wall cracks and tile gaps (mildew-proofing)
  Say goodbye to hiring professionals—save money and gain a sense of achievement!
